Any New Updates on Inspiron 13 7000 (7347) Touch screen problem

I was wondering if there any new news to this touch screen issues.(IE)Is dell upgrading the computer to a newer model.Has Replacement screen been the fix. I just got it and I do see the ghosting issues its not much but its there.I have fully updated this bad boy with all the driver and Bios. I was think of going to get the 7348 I haven't heard of any issues with that ghosting. I did get it for the price but upgrading to the 7348 cost a little bit more than I like. I just wanna know is it worth it.
